                                                                [EXECUTION COPY]

                       FIRST AMENDMENT AND ACKNOWLEDGMENT
                         TO SENIOR MANAGEMENT AGREEMENT

     This First Amendment and Acknowledgment to Senior Management Agreement
(this "AMENDMENT"), dated as of March 5, 2004, is made to the Senior Management
Agreement (the "AGREEMENT"), dated as of February 6, 2004, by and among
Medtech/Denorex, LLC, a Delaware limited liability company (the "COMPANY"),
Medtech/Denorex Management, Inc., a Delaware corporation ("EMPLOYER"), and
Gerard F. Butler ("EXECUTIVE"). The Company, Employer and Executive are referred
to herein as the "PARTIES" and individually as a "PARTY." Each capitalized term
used herein but not otherwise defined shall have the meaning ascribed to such
term in the Agreement.

     WHEREAS, concurrently herewith, the Company and one of its Subsidiaries is
acquiring collectively all of the outstanding shares of capital stock of The
Spic and Span Company, a Delaware corporation ("SNS"), thereby causing SNS to
become a Subsidiary of the Company.

     WHEREAS, in connection with such acquisition of SNS (the "ACQUISITION"),
the Parties desire to amend EXHIBIT B to the Agreement in order to adjust the
EBITDA projections set forth therein so that the adjusted projections take into
account the Acquisition; and

     WHEREAS, the Parties desire to make certain other acknowledgments with
respect to the Agreement and to acknowledge and reaffirm the other terms and
provisions of the Agreement.

     NOW, THEREFORE, effective upon consummation of the Acquisition, the Parties
hereto, intending to be legally bound, hereby agree as follows:

1.   The defined term "Distribution Offset and Contribution Obligation" shall be
     disregarded for all purposes of the Agreement and none of the Parties shall
     have any existing or future obligations or liabilities to another Party as
     a result of such term.

2.   EXHIBIT B to the Agreement shall be replaced and superseded in its entirety
     by the form of EXHIBIT B attached hereto.

3.   Except for the changes noted in Sections 1 and 2 above, the Agreement shall
     remain in full force and effect and any dispute under this Amendment shall
     be resolved in accordance with the terms of the Agreement, including, but
     not limited to, Section 13(g) thereof (Choice of Law).

4.   This Amendment may be executed in any number of counterparts (including by
     means of facsimiled signature pages), which shall together constitute one
     and the same instrument.

                                   * * * * * *

and Acknowledgment to Senior Management Agreement on the date first written
above.
